Abstract

L'invention concerne une méthode permettant d'identifier un dispositif médical allongé situé dans une image bidimensionnelle d'une région étudiée. Cette méthode consiste à filtrer des pixels répondant à des caractéristiques d'intensité prédéterminées pour une mise à l'échelle linéaire, à diviser les pixels filtrés en groupes de pixels contigus, puis à sélectionner dans ces groupes un groupe correspondant au dispositif médical.
